It is an internal computer component that converts line voltage AC power from an electrical outlet to the low-voltage direct current (DC) power needed by system components.

The power supply is a metal box in the rear of the system unit that is attached to the computer chassis and to the system board. Although the power supply is not itself a component of the system board, it is required in order for system components to receive power.

Memory is the component that provides the workspace for a processor. Random access memory (RAM) isv non-olatile memory.

When the power is no longer available, the data stored in RAM is lost.

Computers get very hot when they are running. For this reason, there are a number of cooling strategies employed within a computing device. You are likely to find fans located on several devices within your computer.

_____are located on: the power supply, the video card, and the CPU. In addition, you might have one or more fans built into the computer case. Be sure not to block air flow for these fans. If the computer cannot be properly cooled, it will overheat, causing damage to chips, components, and the motherboard.

___________transfers the heated air from the component to the fan (or liquid cooling system), which then moves the heated air out of the computer case, keeping the inside of the case and the components cooler.

____ a hardware interface that you can use to connect devices to a computer. The port transfers electronic signals between the device and the system unit. The port is either an electrically wired socket or plug, or it can be a wireless transmission device.

a personal computer connection that transfers data one bit at a time over a single wire. Serial connections support two-way communications and were typically used for devices such as fax cards or external modems. These legacy serial ports have either 9-pin (DB-9) or 25-pin (DB-25) male connectors.

Thunderbolt ports are developed by _____

Color of the RCA

It is used in telephone system connections and is not suitable for network connectivity.

a device that connects to a computer to expand the computer’s functionality. This includes devices that enable the user to input, output, store, and share data.

Computers need user input, such as directions or commands, and user interaction with the programs that are included in order to produce something of use.

devices enable the user to get information and data out of the computer. Typical examples include printers, speakers, and displays.

Application software is a software package that enables a computer to function. It performs basic tasks,such as: recognizing the input from a keyboard, sending the output to a display screen or monitor, and controlling peripheral devices such as disk drives and printers.

It is the personal computer component that acts as the backbone for the entire computer system. Sometimes called the system board or mainboard, it consists of a large, flat circuit board with chips and other electrical components on it using various connectors.
